Controlling advanced features of Charts in a TExcelApplication

I've got the following problem: I'm drawing a chart on an excelsheet and want to change some features of it, like the minimum and maximum values of the axes. I have no idea how to do that though. The chart does work with the proper values, it's the make-up that's giving me problems. Any help here is appreciated.
Here's what I've got so far:

Now all you have to do is try to convert these lines to delphi... It's a little tricky but I'm sure you'll figure it out.
Right now I don't have time to do it for you. If you can't do it tell me and in the next couple of days I will try to solve it for you

.MinimumScaleIsAuto = False
.MaximumScaleIsAuto = False

Maybe you should try setting the above for the cahart axis to see what happens. Because theoretically if it is auto it wouldn't matter the values you set as max and min, because it would be autmatic all the time. So probabely your problem comes from that auto property

Delphi (6) doesn't seems to know these kind of parameters. Most of the time you can just copy and paste the VB-source in Delphi, with just some minor changes. But Delphi just won't accept these kind of parameters.

It might be a sollution building a Macro from Delphi, but that won't win the beauty price.

The reason Delphi wouldn't accept parameters like MinimumScale, MaximumScale was because thay weren't defined in the delphi source-files for Excel.

The solution was to add a variant which also was pointed to the Excel workbook.

After this variant you can add all the parameters in the way you see them in the macro's in VB-Script.

Add this line to Var :
WkBook : variant;

Add this line after ExcelApp.Workbooks.Add(xlWBatWorkSheet,0);
WkBook := ExcelApp.WorkBooks.Item[IIndex];

Now you can copy and paste the source according to VB-Script between:
with WkBook do
begin
...
end;

It seems the Variant is a bit slower than using _WorkBook, because the parameters are not checked at designtime but at run-time. So I only use it for graphics and other parameters which aren't availible otherwise.
